IUCN Status: Vulnerable
EPBC Threat Rating: Very high
IUCN Claim: “ Recent research has demonstrated marked detrimental impact of introduced predators: Red Fox (Vulpes vulpes) and feral Domestic Cats (Felis catus)’”
Plains rats remains were found in the foxes’ diet (Pavey et al. 2008; Pavey et al. 2014). Read & Cunningham (2010) described an occasion where more plains rats were captured inside than outside a fenced reserve where carnivores were excluded. Rats were last confirmed at Koonchera Dune, SA, 24 years after foxes arrived (Wallach et al. 202X).
Rats were last confirmed in NSW 63 years before foxes arrived (Wallach et al. 202X).
There are no studies evidencing a negative association between foxes
and plains rats which report data. In contradiction with the claim, NSW
extirpation record pre-dates fox arrival record.
